aef-embedded: USBasp - USB programmer for Atmel AVR controllers

USBasp is a USB in-circuit programmer for Atmel AVR controllers. It simply
consists of an ATMega48 or an ATMega8 and a couple of passive
components.The programmer uses a firmware-only USB driver, no
special USB controller is needed.

Features

Works under multiple platforms. Linux, Mac OS X and Windows

are tested.

No special controllers or smd components are needed.
Programming speed is up to 5kBytes/sec.
SCK option to support targets with low clock speed.
Planned: serial interface to target (e.g. for debugging).
